• Built-in Wake‑on‑LAN support is perfect for remote maintenance, centralized IT control, or scheduled power-ups.
• Low-power offload engine minimizes CPU load with TCP/IP checksum and segmentation offloading.
• QoS & VLAN support with IEEE802.1p priority encoding and VLAN tagging support.
• Space‑saving low-profile design fits both standard and small‑form‑factor cases—low‑profile bracket included
• Diagnostic LEDs enable you to instantly verify link speed and traffic activity.
• Broad OS compatibility ensures that the adapter can be used even in legacy environments (Windows XP/Vista/7/8/8.1/10/11, Linux, Novell)

Recommended Use Cases

• Upgrade desktops with only 10/100 Mbps Ethernet to finish gigabit speed for faster file transfers and more efficient streaming.
• Support remote control of devices with Wake‑on‑LAN in business, laboratory, or server settings.
• Resurrect network connectivity on PCs whose ports or onboard NICs are damaged.
• Add gigabit capability onto Linux-based NAS, older workstation configurations, or small office users with constrained hardware budgets.

Technical Insight

At the core of TG-3468 lies a Realtek-based gigabit transceiver coupled with a lightweight PCIe bus. Automatic speed negotiation and wiring polarity/skew correction are done without user intervention. Two-way data communication reliability is ensured through full-duplex flow control and power-down link detection to conserve energy. Open Source Linux driver support, in addition to classic Microsoft NDIS compatibility, positions it as flexible across platforms—a reliable, cost-effective solution for cable-based networking.
